Foil Lined Glass Beads with larger holes (where to buy or trade)?

I bought some glass beads several months ago that were foil lined in several bright colors. These are about the size of a pony bead, and the holes were larger (like the pony beads). Now I can't find these anywhere. I have seen some packaging that give you a few of these, and then a bunch of the much larger beads. Does anyone here know of where I can acquire these? I would gladly trade some beads (my handmade or others I have) for more of these. Thanks, D.Jean
